HEATER.

Application filed February 18, 1923., Serial No. 619,474

To all whom it may concern Be it known that I, GHARLns F. Lorine, acitizen of the United States, residing at Tonopah, in the county ofNyeand State of Nevada, have invented certain new and useful Improvementsin; Heaters, of which the following is a specification.

This invention relates to heaters, and more particularly to electricheaters.

An object. of the invention is to provide an electric heater having acasing through which air willreadily flow by natural draft.

A further object is theprovision of a pair of inlets, one of which isconnected to an outside fresh air supply.

A further object is the provision of a heater having a casingwith.heatingelements arranged therein and baflle plates disposed in thepath, of the flow of air to cause the air to be brought into contactwith the heating elements.

A furthen object of the invention is the provision of a wedge-shapedcasing larger at'the topor outlet endfthan at the bottom or inlet end.

In the accompanying drawings, I have shown one embodiment of theinvention. In this showing:

Figure 1 is a side elevation, Figure 2 is a front elevation, Figure 3 isa top plan view, Figure 45 is a perspective view of the lower portionshowing the method of'constructing the casing,

Figure 5 is a vertical sectional view on line 55 of Figure 2,

Figure 6 is a similar view on line 6 6of Figure 1,

Figure 7 is a horizontalsectionalview on line 77 of Figure 5, and,

Figure 8 is a similar view on line 8-8 of Figure 5.

Referring to the drawings, the reference numeral 1 designates a hollowbase or support having an inlet opening 2 communicating with the room tobe heated. This opening is controlled by a sliding damper 3, mounted insuitable guides or tracks 4. Op posite the inlet 2, there is provided asecond fresh air inlet 5, having a pipe 6 extending therefrom. The pipe6 is adapted to receive a flexible conduit, which extends to theexterior of the building to supply fresh air. The top of the base isprovided with an opening 7 and the material forming the top is bentupwardly adjacent this openthe interior of the casing. Handles 15 aresecured to the side walls adjacent the top to permit the heater to bemoved to any desired position.

The heating elements are arranged vertically and centrally of thecasing. As shown, they are supported on transverse members 16, formed ofsuitable insulating material and secured to the side walls, as at 17. Andesired type of heating elements 18 may be employed. These elements areconnected to an electric circuit by lead wires 19 and 20, one of whichis connected to the lower ends of the heating elements and the other tothe upper end. As shown, the lead wires extend" through a bushing 21,arranged in the base. The heating elements are connected to each'ot-herat the top and bottom by connecting strips 22.

Suitable bali'les 23 aresecured to the front and rear walls and extendinwardly towardthe center of the casing'and upwardly. These battlescause the air passing through the casing to flow over the heatingelements a number of times during its passage through the casing to beproperly heated."

The casing may be secured to the base in any suitable manner. In Figurer of the drawings, I have shown the casing having openings 24 adjacentits lower edge adapted to receive rivets or other suitable fasteningelements passing through similar openings 25 in the projections 8.

The operation of the device will be apparent from the foregoingdescription. Air enters through the inlets 2 and 5 and flows upwardlythrough the casing. The natural draft caused by the tendency of theheated air to rise causes a ready circulation through the casing. Thefact that the casing is wedge-shaped and larger at the top than at thebottom materially assists this flow of air as the expanded heated air isgiven a larger space through which to pass than the cold air enteringthe casing. The battles 23 are "i ill) arranged that they extend nearlyto the center of the casing where the heating elements are located andin this way, the air is caused to flow over the heating elements anumber of times during its passage through the casing, as indicated bythe arrows in lfiigure 5 of the drawings.

An important feature of the invention is the provision oi a pair ofinlets, one of which is adapted to be connected to an exterior fresh airsupply. By regulating the damper 3, the proportion of fresh air to airwithdrawn from the room for reheating purposes may be controlled. Inthis manner, the desired temperature within the room may be obtained andfresh air supplied at the same time.

It is to be understood that the form of the invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

I claim:

1. In an electric heater, a base having an inlet opening, a casingmounted over said base and con'imunicating therewith, said casingincreasing in width toward its upper end and being provided with anentirely open top, vertically disposed heating elements arranged in saidcasing, and battle plates secured to the walls of said casing.

In a device of the character described, a base having a plurality ofinlet openings, a damper to regulate one of said openings whereby theproportion of air entering each of said opennigs may be controlled, acasing arranged over said base, said casing being provided with an opentop, and baflie plates arranged in said casing.

3. In a device of the character described, a base having a pair of inletopenings, a damper to control one of said openings, a casing mountedover said base and communieating therewith, said casing increasing inwidth toward its upper end and being provided with an open top,Vertically disposed heating elements arranged in said casing, andupwardly inclined baflie plates secured to the walls of said casing andextending inwardly to a point adjacent said heating elements to directair passing through said casing over said heating elements.

i. In a device of the character described, a hollow base provided with apair of inlet openings, an inlet pipe communicating with one of saidopenings, a damper to control the other of said openings, a casingmounted above said base and coi'nmunicating therewith at its lower end,said casing being sub stantially wedge shaped to increase in widthtoward its upper end and being provided with an entirely open top, aplurality of vertically disposed spaced heating elements arranged insaid casing, and upwardly inclined bafl'le plates secured to theinclined walls of said casing and extending inwardly to points adjacentsaid heating'elements, the

ba'lile plates upon opposite sides of said casing being staggered withrelation to each other to direct air alternately from one side of saidcasing to the other through the spaces between said heating elements.

In a device of the character described, a hollow base having an inletopening, a casing mounted over said base and communteating therewith atits lower end, said casing being provided with a plurality of balileplates secured against the inner face of one wall of said casing, theopposite wall of said casing being removable and provided with aplurality of ballle plates secured against its inner face and staggeredwith-relation to said first named bafile plates, and a plurality oiheating elements vertically arranged within said casing between theinner ends of said battle plates.

In testimony whereof, I aflix my si nature in presence of two witnesses.
